Replacing the 600CPSI catalysts, with 100 cell HJS race cats, opens the sound up significantly. Addition of our trademark 20 degree 1D CLR x pipe blends the left and right banks, increasing the tenor range, and giving a fuller, richer vocal, while removing unwanted bass frequencies (drone). The Valvetronic rear silencers, containing our proprietary “Jekyl and hyde” technology, are almost stock quiet on valve closure, to allow for stealthy driving, and zero highway drone. On valve open, the silencer is completely bypassed, allowing the full, untainted V8 Howl ensue.
